ok head is nearly ready to go back on.. it's been crack tested and it's all good. The dude said there's no way that my heads done 300,000kms especially on LPG.
It's already got hardened valve seats.. (is that normal?)

anyway it's been ported and in getting skimmed at the moment.

then I'll go get the cam re-ground and it's all ready.

I was wondering what the best way to clean everything afterwards.. the oil is all mucky from mixing with water.. and the cooling system is all brown and rusty.

run an engine cleaner and a radiator cleaner and flush??

you dont need the EL ECU to use the bbm. Just get a RPM switch from jaycay and your gg.
